Based on my SAR experience a well organized (key word) group provides great experience that would be vital in many disaster/survival situations. You are likely to find out how you react to all kinds of stress, and you will benefit others, as well.

So often, prepping seems to follow a fairly negative, "fortress" mentality in which the prepared fend off the savage, frantic hordes of the cluelessly unprepped. SAR work kind of reverses that. Your experience on "small" SAR level emergencies comes in handy during larger situations.
